Title: Improvements in or relating to the production of vitamin b
IPC: A61K31/525
Filed: 1945-03-20
Abstract: Vitamin B2 is obtained by inoculating a sterile liquid culture medium with a culture of Eremothecium Ashbyii, incubating the inoculated medium with thorough agitation of the medium, e.g. by mechanical means or by bubbling a gas such as air through the culture medium, and thereafter separating from the culture medium the vitamin thus produced.  If desired super-atmospheric pressures may be employed. In examples: (1) a medium of glucose, peptone, yeast and water after inoculation is agitated with a current of air to produce lactoflavine; (2) a medium of glucose, nitritive salts, peptone, meat extract and water is treated as in (1) using mechanical agitation; (3) as in (2) but using both aeration and mechanical agitation.

Title: Dry transfers
Inventor: PIRON JEAN GUSTAVE JULES
IPC: B44C1/17
Filed: 1969-02-10
Abstract: 1,240,794. Transfers. J. G. J. PIRON. 10 Feb., 1969 [21 June, 1968], No. 7099/69. Heading B6C. [Also in Division C3] A pressure-sensitive transfer, which can be used to apply indicia 2 of an ink containing a non-volatile fluid to a receptor surface, comprises a support sheer 1 indicia 2, a layer of pressuresensitive adhesive 3 and a protective surface layer 5 of translucent particles having a refractive index below 1À7, a maximum grain size of 50 millimicrons and a specific gravity below 3. When the transfer is applied to the receptor surface pressure forces adhesive through the layer 5 and wets both the surface and the particles of the layer 5 with adhesive. The particles of layer 5 do not impair the transparency of the applied transfer. Preferably, the support sheet 1 is of a hydrocarbon polymer such as polyethylene or polystyrene and is treated by ion bombardment, after being silk screen printed, with indicia 2, to enhance bonding of the adhesive. The non-volatile fluid in indicia 2 diffuses into the adhesive which covers the indicia 2, and lowers its viscosity, so as to permit the indicia 2 to be adjusted on the receptor surface. Preferably, the adhesive contains a volatile solvent, and contains the particles which form layer 5 in suspension when it is applied. Volatilization of the solvent then carries the particles to the free surface of the transfer, where they form the layer 5. A protective sheer of, e.g. silicone-treated paper may be temporarily placed over the layer 5. Ink formulµ, adhesive formulµ and materials for layer 5 are described with examples.

Title: Improvements in or relating to the manufacture of tubes of fibre-reinforced plastics
IPC: B29C57/00
Filed: 1970-02-16
Abstract: 1293019 Winding tubes KUNSTSTOFFBURO PORTA GmbH & CO KG 16 Feb 1970 [20 Feb 1969] 7400/70 Heading F2P A process for producing fibre reinforced plastics tubes comprises delivering fibre blanks 21, e.g. glass or polyester fibre fleece, and/or webs of interlaced rovings, which may be drawn from a magazine reel 10 and sheared to size on a table 12, to a winding mandrel 22 in the dry state to be wound and impregnated with plastics and subjected to pressure and friction by roller 24 during winding. The width of the blanks corresponds to the required length of the tubes and the length of the blanks may be equal to the circumference of the tube if there is to be a single reinforcing layer or a multiple of the circumference if more layers are required. A set of feed rollers 19, 20 may be used to guide the blanks. As shown, an apparatus for producing the tubes comprises a roller 24 driven by the same mechanism 28 as the mandrel 22 and adapted to rotate at a peripheral speed different from that of mandrel 22, so that the wound tube is smoother at the surface. To this end, the drive may also be so programmed that during the last few revolutions of the winding mandrel, the roller 24 is stationary. The roller 24 partly dips in a tank 26 containing liquid plastics material, e.g. a casting resin, which is conveyed to the mandrel 22 for impregnation of the wound mat. The plastics material if thermosetting, is cured before the wound tube is disengaged from the mandrel. The mandrel itself is mounted for rotation on swivel supports 30 which have limiting stops 34. A method of producing tubes with internal threads is described wherein plastics impregnated fibre rovings are wound into a threadmoulding profile on a mandrel until the surface thereof is flush, and before this cures the required wall-thickness of the tube is built on the mandrel so prepared. The mandrel is finally screwed out, &c. to facilitate this it may initially be treated with a release agent. A method of producing tubes with external threads is illustrated (Figs. 3a, 3b, 4a and 4b, not shown) wherein a thread-moulding roller temporarily carrying spiral fibre rovings is used to transfer the rovings to a semi-cured tube to form helical threads on the tube. Tubes of the invention may be used in chemical plants; tapered cylindrical tubes may be wound which find use as telegraph masts.

Title: Method of and circuit arrangement for determining rotary unbalance
IPC: G01M1/24
Filed: 1976-02-25
Abstract: 1537094 Rotary unbalance machines GEBR HOFMANN GmbH 25 Feb 1976 [30 April 1975]  07495/76 Heading G1N In a rotary unbalance machine a circuit is provided such that if unbalance in a compensation plane cannot be achieved the unbalance value is converted to another compensation plane and/or to a substitution plane in which such compensation can be effected. A four cylinder engine crankshaft to be balanced, Fig. 1 (not shown) is mounted in two spaced apart stand members each having a respective unbalance pick-up and the outputs from which are converted from the planes of the pickup to two outer compensation planes EL, ER spaced a distance l from each other adjacent a respective stand member. The converted signals are then fed to phase sensitive rectifiers and divided into x and y components, Fig. 2 (not shown), the two x components ELx<SP>1</SP> and ERx<SP>1</SP> being fed to the inputs of the circuit of Fig. 3. When the outputs of amplifiers 11, 12 are negative EL 1 , ER 1 , indicating that unbalance compensation is possible in the outer compensation planes EL, ER, the negative signals are fed via amplifiers 13, 14 to control the machine for removing the unbalance in planes EL, ER. If the signals are positive, EL2, ELR2, indicating that compensation in planes EL, ER is not possible, they are fed to computing unit 15, Fig. 4, which carries out a conversion to another compensation plane or to a substitution plane e.g. a middle plane EM at a distance a from the left hand compensation plane. Unit 15 includes two inverting amplifiers 16, 17 connected as shown to each other and a potentiometer 18 for setting the unit in accordance with the distance a so that after the conversion operation a voltage EM 1  and ER 3  appear at the outputs of amplifiers 16, 17. The signal EM 1  can be used directly for unbalance compensation in the substitution plane or planes EM whereas the output voltage ER3 if negative and indicating that compensation can be carried out in compensation plane ER is fed via inverting amplifier 19 (output ER 5 ) to the input of amplifier 14 where it is added to ER 1 . If however ER3 is positive indicating that compensation cannot be made in plane ER the voltage is fed via inverting amplifier 19 to an inverting amplifier 21 where the signal is converted to ER 4 À1/a using voltage divider 22. This converted value is then added to the value EM 1  at the input of inverting amplifier 20 so that the output EM is the total compensation for the middle substitution plane or planes. In addition the value ER 4 À1/a is applied to inverting amplifier 23 together with the value ER 4  so that the value ER 4 (1/a-1) is obtained and this is added at amplifier 13 to the value EL 1  to give the total compensation for the compensation plane EL. An identical circuit to Figs. 3 and 4 is used for the y components.

Abstract: 721,374. Blade wheel propellers. VOITH, GES., J. M. March 26, 1952, [April 19, 1951], No. 7784/52. Class 4. A blade wheel propeller with a control disc coupled so as to be driven uniformly with the wheel member, and coupled to the blades, in each case by a rod system, is characterized in that the control disc is supported by the inner ends of two armed levers, mounted in the wheel member so as to be rotatable about pins parallel to the axis of the wheel member. In Fig. 2, the control disc 7 comprises two annular discs connected by a central tube, and by rotatable crossheads 5 adapted to receive slidably the tubular ends of bell crank levers 4, pivoted at 3 to the wheel structure, and whose other ends control, by levers 9, the blade pitch. Blocks 17 are attached to pins fast to the control disc 7, and slide in slots 14 of an X-shaped driving disc 13, allowing the control disc to move relative to the driving disc along a direction joining the blocks. Blocks 18, relative to which the disc 13 may slide, are on pins fast to the wheel structure, and allow the driving disc 13 and control disc 7 freedom of movement in the direction joining blocks 18. A controlling member which does not rotate with the wheel has one end pivotally secured within the central tube member of the control disc, to adjust the disc to an eccentric position along any radius of the wheel, thus controlling the phase and amplitude of the cyclical blade feathering, through the cyclic oscillations of levers 4. Preferably only three levers are used to support the control disc, any others sliding in cross heads which have play relative to the control disc parallel to the axis of the wheel. One each of blocks 17 and 18 may be mounted on its pin by a ball and socket joint, and the arms of the levers 4 may be universally mounted in their respective cross heads 5.
